1.利用生理性色泽鉴别杂交稻种子有一个共同点,就是种子的内外颖上面略带有不均匀的黄褐色等生理性杂色,谷尖一般带有紫色,而常规稻谷尖无色,内外颖颜色均匀一致。如有个别因受病虫危害或肥水管理不当造成有一些杂色,但与杂交种子的生理性杂色不同,比较容易识別。 2.利用不同授粉结果来判别水稻杂交种子是属异花授粉,柱头外露率高,在授粉后谷壳内外稃的夹缝
1. The use of physiological color to identify hybrid rice seeds have one thing in common, that is, the seed inside and outside the Ying slightly uneven yellowish brown and other physiological variegated, Valley tip generally with purple, while the conventional rice tip colorless, both inside and outside Ying color uniform. If some due to pest insects or fertilizer caused by improper management of some variegated, but with hybrid seed physiological variegated different, easier to identify. The use of different pollination results to determine hybrid rice seedlings is cross-pollination, stigma exposed rate high, pollination in the hull inside and outside the gap
